UNITED STATES PATENT oFFica- OLE O. KOLSTAD, OF DULUTH, MINNESOTA.

' MAIL BOX.

Application filed September 29, 1922. Serial No. 591,388.

To all whom it may concern:

Be it known that I, OLE O. KoLsTAD, a citizen of the United States, residing at Du-. luth, in the county of St. Louis and State of Minnesota, have invented new and useful Improvements in Mail Boxes, of WlllCll the This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. I

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side view of the box showing the same in use.

Figure 2 is a longitudinal sectional view through the box.

Figure 3 is a rear. view.

Figure 4 is a front view.

Figures 5 and 6 are detail views.

As shown in these views the body portion of the box 1 has an extension 2 laterally disposed at its upper part. The bottom of the extension extends at right angles to the adj acent side of the box, the top being curved, as at 3, said top extending over the extension. This curved top acts to shed water and snow. The front of the extension is left open, as at 4:, and said opening is adapted to be covered by a hinged lid 5 which is flanged at its sides and bottom for overlapping the parts of the extension and the upper edge of the lid is provided with a flap 6 for making a water tight closure with the curved top. A curved plate 7 is provided for preventing a person taking mail from the box, said plate'being pivoted at 8 with its curved portion overhan ing the bottom, thereby mail and the like t at is not heavy enough to an thisplate will be slidably a posited in the box. A'substantially Vshaped spring. 9 is secured to the box and projects under the extension 2 as shown. This spring is adapted for receiving outgoing mail. An opening 10-is formed in the lower rear side of the box, said opening being closed by a door 11 which may be locked by a padlock engaging opening in the angle part 12 which is arrangedto pass through the slot 13 in the door. A flap 14: is provided for cover: ing the hinged joint to prevent the entrance of water. The opening 10 has its lower edge slightly above the bottom of the box to leave a flange 15 for preventing the. mail from dropping out when the door is opened. A substantially U-shaped reinforcing strip 16 is fastened upon the inner face and side walls of the box adjacent the lower end and a screw 17 passes therethrough for engaging a post 18 or the like, the upper end of whichv is spaced from the bottom of the extension to allow an appropriate space for operation arm 18 is pivoted to one side of the'box, as at 19, said arm having a weighted extension 20 which extends at an angle fromthe arm and acts to hold the arm in either itsraised or lowered position, as shown in full and dotted lines in the drawings. When this arm is in raised position it will indicate that mail is in'the box. A stop 21 is provided for limiting the movement of the arm.

As will be seen from the above the mail carrier can easily deposit mail in the box or take the mail therefrom and after the mail is deposited in the. box the plate? will pre- 1 vent any unauthorized person taking the mail therefrom. The box is entirely weather proof so that there is no danger of the mail being injured by the elements, and the peculiar construction of it permits the box to be placed on a post or the like so that the mail can be easily deposited therein and removed therefrom.

having a laterally disposed-extension formed atits upper end and the rear Wall of the box being curved over said extensiongto form the top thereof, a flanged closure for the extension and being hingedly secured to the curved top, a substantially U-shaped reinforcing strip secured to the inner face and side Walls of the box adjacent its bottom, a fastening element passing through the reinforced portion intermediate its ends and securing the box to a postso as to position the said extension in spaced relation from the top of the post and a substantially V-shaped spring having'its ends secured to the box between the extension and post respectively for the purpose-specified 2., A mail box having an opening in its rear Wall at its bottom, a hinged slotted closure for the opening, a flap depending over the hinged end of theclosure, an openextension formed on the upper end of the box, a flanged hinged. closure for the extension, a flap extending inwardly from the upperendiofrthe flanged closure and an apertured angle shaped projection secured to the bottom of the box and passing through the Slotted closure for the purpose specified.

3Q A mail box of thecharacter described comprising a body portion, a lateral extension formed at the upperend of the body, portion and the rearvwallz-ofthe body p 1.- tion being-curved to provide the top Wall for the extensiomand a curved plate pivotally securedintennediate itsoends at the: juncture of the body portion and extension respectively with its curvedv portion overhanging the bOttOIILOf the box whereby mail that is heavy enough to tilt the plate Will be=slidably deposited therein. 1

In testimony whereof I afix my signature:
